Now the great thing about this app for many is the ability to connect it to your Snapchat account.

Snapchat is probably the most popular social media site for young people right now but it is difficult to find new friends unless you know their username.

Parents of teens attending Salesian Secondary College in Pallaskenry have been warned to stay vigilant.

Chairperson of the Parents’ Association Catherine Fitzgerald added: ‘Snapchat is a very hard one for parents to monitor, because the pictures more or less delete themselves.’ A Garda spokesperson said: “Our advice would be for people not to share any personal information with strangers online”. The app can be purchased on Apple and Android devices.
